In the embodiment of my invention which To all whom it may concern.

Be it known that I, JOHN JUNKUNO, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Locks, of which the following is a specifi- My invention relates to looks and has'particular reference to combination locks which may be used in padlocks, safes, and the like.

in Patent No. 948,280, issued to me on the main casing 10 of the lock is substantially cylindrical and is provided with a forwardly extending flange 11 which in turn has the beveled lip 12. Holes l3 and 14 are drilled in this casing for the accomm0- dation of the locking member or staple 15. As most clearly shown in Fig. 3, an annular groove 16 is cut in the front face of the casing 10 and a locking ring 17 is adapted to be rotated in this groove. The central part of the casing-1O has a circular recess 18 in which the locking disk 19 is adapted to fit and within whiclrthe same may be rotated. An annular space 20 is left between the locking ring 17 and the Flange 11 so that if this flange becomes distorted or is subjected to a blow, the effectwill not reach the locking ring 17. The side of the locking disk 19 has a rabbet 21 which is engaged by the front face ring 22 which has the beveled edge 23 held in position by the lip 12 which is rolled over the face ring 22 after the same has been placed in position. The locking disk lthhas the knob Qet by means of which the disk may be readily rotated. On the side of the locking disk 19, is the pin 25 which is adapted to engage the inward projection 26 on the locking ring 17 and thereby move the same to any desired position.

' The longer arm of the locking staple 15 has the grooves 27 and 28 which are engaged [by the ring 17 which thus serves to prevent the staple from being pulled out. The shorter arm of the locking staple has the groove 29 for a similar purpose. In the locking ring 17 are the recesses 30 and 31 which, when the ring is rotated to a suitable position, will register with the longer arm lock was disclosed in which a' plurality of concentric rings were used, each ring having on its periphery one or more recesses. When the various rings were brought into proper relation, the staple of the lock could be moved b'ut when the recesses in the ring werein other positions, the locking staple was engaged by the rings which passed through grooves in the staple which was thus held securely in position.

In the improved form of lock which forms the subject matter of my present invention, I employ. only a single locking ring. The central disk which is rotated in working the combination, is provided with a pin on its periphery which is adapted to move the locking ring into the proper position. On rotating the disk in the opposite direction, the disk itself is moved so that a recess in its under surface will allow the movement of the locking staple which is otherwise held in position either by the locking ring or by the engagement of the edge of the disk with a shoulder formed by a suitable recess in the staple. The staple is also provided with a recess extending partially around its periphery. thus enabling it to be turned after one end has been freed from engagement with the lock itself.

it, will be apparent that this construction is very simple and cheap, no springs or other complicating parts being used, while at the same time the lock is very durable on account of the substantial nature of its parts. These and other advantages of my invention will be more clearly understood by reference to the accompanying drawings in which:

l igurc 1 is a front elevation of my iml 17 also has the recess 32 which registers is illustrated in the accompanying drawings,

of the locking staple 15; the locking ring combination is opposite the in with the shorter arm of the locking staple 1.3 when the recesses'30 and 31 register with the longer arm thereof.

As most clearly shown in Figs. 3 and 1, where the locking disk 19 engages the front face of the longer arm of the locking staple 15, the latter is provided with a recess having a flat surface, which thus acts as an additional means for preventing the withdrawal of the staple on account of the inner shoulder of this recess with the periphery of the locking disk 19. A. recess 32 is made continuous with the recess on the front of the longer arm of the locking staple 15,v and extends rearwardly on the outer side of this arm. The object of recess 32* will be explained hereafter.

As best shown in Fig. 5, the rear face of the locking disk 19 has a recess 33 which terminates in the shoulder 34: and the front face of the disk has a scale marked around its periphery, while on the front face ring 22 is themark 35 by means of which the proper rotation of the lockingdisk 19 may be regulated.

Having thus of my improved lock, be readily understood. Assuming hat the" locking staple 15- 's in the'position shown in the drawings, it may be released by first rotating the locking disk 19 in one direction until by means of engagement of the pin 25 with the projection 26, the locking ring 17 is moved to such position that the recesses and 31 register with the longer arm of the locking staple 15 and the recess 32 re isters with the shorter arm thereof. his result is, of course, accomplished by rotating the locking disk until the proper numher on the scale registers with the mark on the front face ring 22. The locking disk 18) is now rotated in the opposite direction, the pin :25 becoming disengaged from the i l l I described the construction its operation 1 ay now projection 26 and leaving the locking ring 17 in the position in which t has ust been second number of the ark 35, the recess 33 has its axis in the same plane as the axis of the-longer arm of the staple 15, and the peripl'iery of the locking disknow no longer serves to retain the staple 15 in its locked posititm, but allows the same to be moved outwardly until the shoulder, at the end of the recess at the front of the longer arm of the locking staple, engages the shoulder at. the end of recess When this takes place, the shorter arm of the staple has already become disengaged f1 om the main casing 10. The staple may now be turned through an angle of 90 degrees, the recess 32 serving to allow such rotation, the portion of disk 10 between the sl'ioulder and the periphery of the disk l9 coming to occupy moved. \Vhcn the ing a' lateral a position within this recess, the shoulder 35 preventing further outward movement of the locking staple. The lock, of course, may be locked by moving the staple into the position shown in the drawings and then rotating the locking disk 19.

It will be apparent that many changes could be made in the exact construction of the parts which I have described without departing from the spirit of my invention.
